AFMSSr. DevSecOps Engineer Security Clearance

Position: AFMS3 Sr. DevSecOps Engineer with Security Clearance
Location: Highland Home

Position Summary We are seeking a Senior Dev Ops Engineer to drive infrastructure-as-code and CI/CD pipeline engineering across our cloud environments. This role owns the design, implementation, and continuous improvement of Terraform-managed infrastructure and the automated build/test/deploy pipelines that ship it, working closely with development and platform teams to increase deployment velocity, reliability, and security. The ideal candidate is a hands-on engineer who can independently design and deliver infrastructure and pipeline solutions with minimal oversight.

Key Responsibilities Infrastructure as Code (Terraform)
* Design, build, and maintain modular, reusable Terraform code for provisioning and managing cloud infrastructure across dev, staging, and production environments.

* Implement and enforce Terraform state management, workspace strategy, and module versioning to support multiple teams safely.

* Establish and follow IaC best practices: code review standards, automated plan/apply workflows, drift detection, and policy-as-code guardrails.

* Identify and remediate technical debt in existing infrastructure code to improve maintainability, security, and cost efficiency.

* Collaborate with architecture and security teams to ensure infrastructure design aligns with security baselines and compliance requirements. CI/CD Pipeline Engineering
* Design, build, and continuously improve CI/CD pipelines that automate build, test, security scanning, and deployment of applications and infrastructure changes.

* Standardize pipeline patterns across teams/repositories to reduce duplication and increase deployment reliability and speed.

* Implement deployment safety mechanisms: automated testing gates, canary/blue-green deployments, rollback automation, and release approvals.

* Partner with development teams to identify and remove build/deploy friction, shortening lead time from commit to production.

* Monitor pipeline health and performance, proactively resolving bottlenecks and failures. General Engineering & Operations
* Participate in on-call rotation and incident response for infrastructure and deployment-related issues; contribute to blameless postmortems and follow-through on action items.

* Document infrastructure designs, pipeline architectures, and operational runbooks for team use.

* Mentor junior engineers on Terraform and CI/CD best practices as opportunities arise.

* Stay current with evolving Terraform, cloud provider, and CI/CD ecosystem capabilities, and bring recommendations back to the team.

Required Qualifications
* Active DoW Secret clearance (or higher) required at time of hire.

* 5+ years of Dev Ops/infrastructure engineering experience.

* Deep, hands-on production experience with Terraform for infrastructure-as-code across multi-environment cloud deployments.

* Proven experience designing and operating CI/CD pipelines (Git Lab CI, Jenkins, Code Pipeline, or similar).

* Strong working knowledge of core cloud services (networking, IAM, load balancing, monitoring/logging).

* Experience with version control workflows (Git) and code review practices for infrastructure and pipeline code.

* Solid scripting/automation ability (Bash, Python, or similar) to support pipeline and infrastructure tooling.

* Strong written and verbal communication skills; able to document and explain technical decisions clearly.

Preferred Qualifications
* Experience with policy-as-code tools (Sentinel, OPA/Conftest) and Terraform automation platforms (Terraform Cloud/Enterprise).

* Experience with containerized workloads (Docker, ECS, Kubernetes) as pipeline deployment targets.

* Familiarity with observability stacks (Prometheus/Grafana, Datadog, Cloud Watch) for infrastructure and pipeline monitoring.

* Relevant certifications (Hashi Corp Terraform Associate, AWS Certified Dev Ops Engineer, or equivalent).

* Prior experience supporting federal, DoD, including familiarity with STIGs/CIS benchmarks and RMF processes. GDIT IS YOUR PLACE At GDIT, the mission is our purpose, and our people are at the center of everything we do.
